Monitoring Pressure, Flow, Temperature, Humidity, etc. via Communication Output■ OUTLINE
This product is a plug-in type communication unit, which can isolate 2 circuits ofDC current input or 2 circuits of DC voltage input to communication output.
Usually used for monitoring analog signal of pressure, flow, temperature andhumidity, etc. via RS-485 communication output (Modbus RTU).
■ FEATURE

 Withstanding voltage for input 1, input 2, communication output, aux. power andouter case is AC2000V (50/60Hz) in 1 minute insulating.
 Power supplied operation and communication operation can be checked by LED(green).
 Accuracy of converting is ±0.2％ and below.
 Standard socket is attached (Socket type name：FW11).
